4.Clinical Study on Compound Sophorae Flavescentis Radix (Kushen) Injection Combined with Intraperitoneal Chemotherapy for Advanced Ovarian Cancer with Malignant Ascites
Chinese Journal of Information on Traditional Chinese Medicine 2015;(5):25-28
Objective To evaluate the clinical efficacy of compound Sophorae Flavescentis Radix (Kushen) injection intravenous drip combining carboplatin intraperitoneal injection in treating advanced ovarian cancer with malignant ascites. Methods Totally 160 patients with advanced ovarian cancer with malignant ascites were randomly divided into compound Kushen injection intravenous drip combining carboplatin intraperitoneal injection group (observation group) and carboplatin intraperitoneal injection group (control group). Clinical efficacy observation and evaluation were conducted from malignant ascites condition, changes in living quality (KPS score), T lymphocytes subsets and changes of the NK cells in blood samples, pain-relieving efficacy, and toxicity response. Results There were significant differences in malignant ascites between the two groups (P<0.05), with treatment group showing better improvement than the control group. In improving quality of life, the observation group had precedence over the control group (P<0.01). After treatment, CD3+, CD4+, CD4+/CD8+, NK (CD16+CD56+) in control group were obviously less than the observation group (P<0.05). The pain-relieving efficacy in the observation group was superior to that in the control group. Compared with the control group, the observation group had less gastrointestinal reaction and bone marrow suppression, with statistical significance (P<0.05). Conclusion Compound Kushen injection intravenous drip combined with carboplatin intraperitoneal injection in treating advanced ovarian cancer with malignant ascites can effectively improve the immune function and quality of life, and can be used for adjuvant chemotherapy with less side effects.

Objective To investigate the role of glycogen synthase kinase-3β (GSK-3β) in the trafficking of NR1-containing N-methyl-D-aspartate receptor (NMDAR) and NR2B-containing NMDAR in the spinal cord in rats with incisional pain (IP) and remifentanil-induced hyperalgesia.Methods Twenty-four male Sprague-Dawley rats,aged 2-3 months,weighing 240-260 g,were randomly divided into 3 groups ( n =8 each):control group (group C),remifentanil group (group R) and GSK-3β inhibitor TDZD-8 group (group TDZD-8).A 1-cm longitudinal incision was made in the plantar surface of the left hindpaw in anesthetized rats.In group C,dimethyl sulfoxide (DMSO) 2 ml/kg was injected and then the normal saline (equal to the volume of remifentanil) was infused for 60 min via the caudal vein.In group R,DMSO 2 ml/kg was injected before IP was made and then remifentanil was infused at a rate of 1.2 μg· kg- 1 ·min- 1 for 60 min.In group TDZD-8,TDZD-8 2 ml/kg was injected before IP was made and then remifentanil was infused at a rate of 1.2 μg·kg-1 ·min-1 for 60 min.Paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) were measured 24 h before infusion of normal saline or remifentanil and at 2,6,24 and 48 h after intravenous injection.The rats were sacrificed after the last measurement of the pain threshold and L4-6 segment of the spinal cord was removed to determine the expression of NMDAR NR1 and NR2B subunits in cell membrane (s) and cytoplasm (i) in the spinal cord by Western blot analysis.The ratios of sNR1/iNR1 and sNR2B/iNR2B were calculated.Results Compared with group C,PWT was significantly decreased and PWL was significantly shortened,the expression of sNR1 and sNR2B was up-regulated,the expression of iNR1 and iNR2B was down-regulated,and the ratios of sNR1/iNR1 and sNR2B/iNR2B were significantly increased in groups R and TDZD-8 (P < 0.05).Compared with group R,PWT was significantly increased and PWL was significantly prolonged,the expression of sNR1 and sNR2B was down-regulated,the expression of iNR1 and iNR2B was up-regulated,and the ratios of sNR1/iNR1 and sNR2B/iNR2B were significantly decreased in group TDZD-8 ( P < 0.05).Conclusion GSK-3β is involved in the regulation of trafficking of NR1-containing NMDAR and NR2B-containing NMDAR from cytoplasm to cell membrane in the spinal cord in rats with IP and hyperalgesia induced by remifentanil.

Chinese Pediatric Emergency Medicine 2014;21(3):140-142
Objective To investigate the clinical characteristics,diagnosis,treatment and prognosis of hypertrophic cardiomyopathy(HCM) in children.Methods Twenty-five cases of children confirmed with HCM in Beijing Children's Hospital from October 2000 to September 2013 were analyzed retrospectively through their clinical manifestations,laboratory tests,treatment and prognosis.Results HCM was found to be more common in older children.The average age of the patients in the studied cases was 8 years and 9 months and the male to female ratio was 3.1:1.Their clinical manifestations were as the follows:5 cases with shortness of breath and fatigue,4 cases with chest tightness and long breath,3 cases with precordial discomfort,5 cases with cough and wheezing and found to have cardiac abnormalities,8 cases found with asymptomatic heart murmurs with no other symptom,2 cases with syncope episodes,6 cases with a clear HCM family history,3 cases with a family history of infant deaths (specific condition not clear).ECG:18 cases showing left ventricular and/or right ventricular hypertrophy and ST-T changes,3 cases showing abnormal Q waves,2 cases showing ST-T changes,2 cases with Ⅰ ° atrio-ventricular block,1 case with left bundle branch block,and 1 case with left anterior division block.Cardiac enzymes were elevated in 5 cases.Chest X-rays showed enlarged heart shadow in 17 cases.Echocardiography revealed non-obstructive hypertrophic cardiomyopathy in 23 cases and obstructive hypertrophic cardiomyopathy in 2 cases.Left ventricular systolic function was decreased in 2 cases,and diastolic dysfunction in 3 cases.Twenty-one patients took oral metoprolol,1 patient took verapamil,1 patient took propranolol and 2 patients took no medication.The follow-up period of 2 months to 13 years witnessed 2 cases of death and 23 cases of survival.Conclusion HCM in children lacks specific clinical manifestations and the conditions of the patient are usually severe with progressive development.HCM is one of the main reasons of sudden death in adolescent,with poor prognosis.
9.Observation of efficacy of the self-made traditional Chinese medicine combined with brufen in treatment of cervical spondylosis
Chinese Journal of Primary Medicine and Pharmacy 2011;18(3):339-341
Objective To observe the effect of the self-made traditional Chinese medicine combined with brufen in treatment of cervical spondylosis. Methods 170 cases were divided into the treatment group(85 cases) and the control group(85 cases) randomly. The control group was treated with brufen. Patients in treatment group received routine treatment plus the self-made traditional Chinese medicine. After the treatment, the curative effect, aches and coma were analyzed. Results The total effective rate was 94. 1% in treatment group but 84. 7% in control group.Difference between the two groups had statistical significance( x2 = 3.997,P < 0. 05). The integrate of 1 ahes and coma were ( 7. 8 ± 2. 4), (9. 4 ± 2. 1 ) marks and ( 2. 5 ± 0. 6), (3. 1 ± 0. 9) respectively, it was lower than before treatment(11.9 ±2.3) ,(12.3 ±2.9) marks and (5.6 ± 1.4) ,(5.3 ± 1.2) marks. Aches and coma showed a great difference after treatment from those before treatment( t = 34. 641、6. 159、6. 173、6. 080,all P <0. 05 ). Aches and coma were lower then those of control group(t =9. 283、3. 464,all P <0. 05). No severe adverse reaction occurred in two groups. Conclusion The self-made traditional Chinese medicine combined with brufen is effective to treat aches and coma in cervical spondylosis. The method was feasible for treat aches and coma in cervical spondylosis.
10.Epithelial-mesenchymal transition and drug resistance of tumors
Chinese Journal of Clinical Oncology 2013;(17):1068-1071
Differentiated epithelial cells could be transformed into mesenchymal cells through the epithelial-mesenchymal transi-tion (EMT), which is important for tumorigenesis and metastasis. Recent studies suggest that EMT is closely correlated to the resistance to chemotherapy of tumors. This chemoresistance could enhance tumor malignancy, which includes the induction of the EMT pheno-type. The paper reviews the research progress on EMT and its association with drug resistance of tumors.
